  • [HOW TO] Jailbreak Your iOS 5.1.1 Device With Absinthe 2




    {last updated May 30, 2012}

    This OS X and Windows guide will teach you how to jailbreak various devices using Absinthe 2. The current version of Absinthe is 2.0.4. Note this is an UNTETHERED JAILBREAK, meaning you can reboot your phone just like you normally would.

    This guide should be used with the following device/firmware combinations (if you're not sure, here's how to find your iOS firmware version and how to find your iOS device type):
    • iPhone 4S | 5.1.1
    • iPhone 4 | 5.1.1
    • iPhone 3GS | 5.1.1
    • iPod touch 3G | 5.1.1
    • iPod touch 4G | 5.1.1
    • iPad | 5.1.1
    • iPad2 | 5.1.1
    • The New iPad | 5.1.1

    The Chronic Dev Team has released Absinthe 2. Absinthe 2.0.4 works with Mac, Windows and Linux computers. The tool jailbreaks most devices running iOS 5.1.1.

    Since the jailbreak is intended for the newer software, it is recommend that you do a full DFU mode update from your previous firmware as this will overwrite any previous jailbreak data on your device and allow you to start fresh. After you have updated your firmware to iOS 5.1.1, you can follow the steps of this guide to jailbreak any of the devices listed above, in an untethered fashion.

    1. Begin by downloading the Absinthe 2.0.4 application for your operating system:

    2. Launch the downloaded file to open a virtual disk where you can either open Absinthe immediately, or drag the Absinthe application to your applications folder for future use.



    3. After you have opened Absinthe, plug in your iOS device and take note of how Absinthe auto-detects the device you plug in and the firmware it is running. If it is correct, click on the jailbreak button.



    4. After clicking the jailbreak button, the whole process is mostly automatic. Absinthe will jailbreak the device for you without the need to enter DFU mode. During the process, Absinthe will show many different stages of the jailbreak process as shown below.



    While Absinthe is jailbreaking your iOS device, the screen will appear as if the device is beginning a restore. This is normal – do not panic as nothing is going terribly wrong. Additionally, do not unplug the device or start using it until Absinthe says, “Done, enjoy!” Once it says this, the jailbreak is finally finished!

    After the jailbreak is finished, there is one more step. You must unlock your iOS device and find Cydia on your home screen. Launch it and Cydia will start the process of preparing the filesystem. This process takes a while, so be patient. While Cydia is doing this, your screen should look like the image below:



    When Cydia finishes preparing the filesystem, the device will respring and you can start downloading and enjoying your favorite Cydia tweaks on your newly jailbroken iOS 5.1.1 device. Since the jailbreak is untethered, you can reboot your device freely and your jailbreak will remain. If you are new to the realm of jailbreaking, check out our Staff favorites post to learn about some awesome iOS applications and Cydia tweaks!

      so what u are saying is that i have to run abstine and jailbreak my iphone again everytime i restore my phone ?

      if thats so, then how do keep my stuff that are on my iphone when i want to jailbreak it?
      because on a tutorial that i found in the internet, it said that make a backup of ur phone before u jailbreak, in order to keep ur apps and al of that stuff after the jailbreak

      No.
      Nothing, you get your backup restored.
      The jailbreak will remain.

      It was a fluke, you or the JB did something wrong.

      You should restore and reJB.
      so it the jailbreak should remain after restoring from a backup?

      You would want to jailbreak again whenever you restore or upgrade your device. Unless you use a custom firmware, wherein it is a simultaneous restore/upgrade and jailbreak. Either way, a jailbreak has to be applied again.

      You keep your stuff by backing them up. Transfer purchases, sync, create a backup in iTunes. Jailbreak apps/tweaks can be backed up with PkgBackUp or other backup packages provided in Cydia. iTunes will not back JB items up. The reliability of the backup packages in Cydia are questionable in some instance, expect to have to reinstall your jailbreak items regardless.

      It should, assuming everything went well.

      ow ok thanks
      so right now i have to jailbreak, and if i wanted to restore from backup i have to use some cydia packages instead of itunes?

      and one more thing, how to i unlock my phone, to get other SIM cards to work with it?

      No, if you restore from backup that's that. Cydia packages like PkgBackUp backs up your prior Cydia tweaks if you chose to back them up before restoring/upgrading.

      You need to use iTunes to create and/or restore from backup.

      Unlocking is entirely dependent on your baseband version and your device model. That general question cannot be answered without that info.

      Why? Just restore from backup? It shouldn't be a problem. If you're really set on jailbreaking first, then set it up as new. Then after you jailbreak it, you can go to iTunes and select to restore from a backup.

      No it won't. Restoring from backup isn't the same thing as a factory restore.

      No problem. What's the baseband? I am assuming since you're on 5.1.1 you also updated the baseband...you likely can't unlock it. But you can check anyway...it's in your settings under general, about, modem firmware

      so the modem firmware is the base band?

      No software. No chip. No unlock except an official unlock and that probably won't change anytime soon. Your only options are calling the carrier the phone is locked to and ask them if they will do it or try that website to see if they can get it done.

      i know
      im asking that what is the latest baseband that CAN be unlocked currently?

      lets just assume i had an older base band, that could be unlocked without that website and that kinds of stuff, lets say that i my self wanted to unlock it personally, how can that be done?

      Check the "can I unlock" link in my signature. Basically 4.10.01 is the latest iPhone 4 baseband that can be unlocked by any other means other than an official unlock.
